Here's some past examples of True Pundit "journalism" for you.

  * Clinton secretly wearing mini stealth earbud to receive answers from her team during the debate

  * Clinton was using secret hand signals to tell Lester Holt what to say

  * Claims Clinton had a medical issue during the debate and Trump mouthed the word "Seizure"

  * Offers a $1m reward (as if a website like True Pundit has $1m) for Clinton's medical records, suggesting that she has "dementia, post-concussion syndrome, Parkinson’s disease, brain tumor, brain injury, complex partial seizures, and/or many more alleged ailments" and is followed by a doctor disguised as a Secret Service agent carrying an autoinjector of diazepam.

Um, have you seen their Twitter feed lately? It's a nonstop feed of anti-Clinton propaganda, half of it retweets, a lot of the claims so bad that even Wikileaks supporters on the Wikileaks Reddit sub have been calling them out on it. It's morphed into Breitbart.

They're even repeating Trump's "rigged election" lines:

There is no US election. There is power consolidation. Rigged primary, rigged media and rigged 'pied piper' candidate drive consolidation.

Comment Re:AI is not real thinking (Score 1) 200

The only AI's that have to appear human are AI's that are *intended* to pass for human. AI is artificial intelligence, that is, intelligence that happens to be artificial. Full stop. Nothing more, nothing less. Any human-like characteristics that we desire to assign to an AI are entirely independent to what AI actually is, by definition, and are only circumstantially related to it in the sense that an as-yet unprecedented sophistication level of AI would need to be achieved to implement many of those characteristics.

Yes. I've run numbers before. No, I'm not going to be bothered to do them again for a Slashdot chat on a thread that's rapidly becoming out of date. Feel free to do your own if you doubt me. Take a sampling of solar plants with a realistic capacity factor and a sampling of hydro plants with a realistic capacity factor, and compare. You'll need a broader sampling on hydro because solar thermal plants are "fairly" consistent (with the exception of compact linear fresnel plants, of which last I checked there was only one), while hydro reservoir sizes vary wildly for a given output.

No, a RTG is distinctly different from a nuclear reactor in almost every single way. They do not involve chain reactions. They do not involve neutrons to any significant degree. Moderation, cross section calculations, etc don't even come into play. It's just a ball of material that stays hot due to capturing its own alphas. RTGs are not considered nuclear reactors. There is no wiggle room on this; they're an entirely different class of spacecraft power systems.

RTGs scale down quite well. They're also, however, about as far on the opposite side of the affordability spectrum as you could possibly get.

There have been actual nuclear reactors used on spacecraft in the past, as I wrote, primarily by the Soviets. But they're anything what you'd consider a cost effective design for civilian power generation.

Higher fissile number density = higher enrichment = nonstarter. Fine for submarines, not for civilian power. Re, reflector, you still have to deal with free path issues when determining overall reactor size. The more you're spending on inert mass relative to how much power you're getting, the worse your economics. Plus your reflector is contributing to (n, gamma) and other neutron consuming reactions (although it's possible to use a moderator that you need anyway (say graphite) as a reflector... although there are issues with that as well to deal with)

You'll note that I mentioned and agreed with the mass production argument - if fission power is going to have an actually sustainable renaissance, I would expect modular reactors to be the means. But I nonetheless questioned whether that could be enough to overcome the basic issues on top of the additional challenges that a small modular reactor imposes.

Energy density (with respect to time) - J/m^2-s or equivalent.

As for "Who cares?" The GP for one. Me for two. Most people on Earth as well. The more land that is used up, the less you have for other purposes, be that for humans (agriculture, forestry, mining, grazing, etc) or natural habitat. It hits doubly that reservoirs target land defined most notably by the following characteristics:

1) Large river
2) Deep ravine/basin
3) Significant altitude change

In short, they often tend to be the areas most important to wildlife, often locally-unique habitats, as well as the most scenic areas within a given location - areas responsible as well for significant mobilization of sediment and oxygenation of water.

Solar, by contrast benefits most from environments full of endless identical flat wastelands. The more mundane and barren, the better.
